Division of Integers Rules and Examples
Question 1: Find the value of ||-17|+17| / ||-25|-42|
Solution:
||-17|+17| / ||-25|-42|
= |17+17| / |25–42|
= |34| / |-17|
= 34 / 17
= 2
Question 2: Simplify: {36 / (-9)} / {(-24) / 6}
Solution:
{36 / (-9)} / {(-24) / 6}
= {36/-9} / {-24/6}
= – (36/9) / – (24/6)
= -4/-4
= 4/4
=1
Question 3: Find the value of [32 + 2 x 17 + (-6)] ÷ 15
Solution:
[32+2 x 17+(-6)] / 15
= [32+34+(-6)] / 15
= (66-6) / 15
= 60 / 15
= 4
Question 4: Divide the absolute values of the two given integers?
Solution:
The quotient of the absolute value of integer +24 and the absolute value of integer -8
From the rules given above, dividing the integers with different signs gives the final result as negative.
When positive(+) 24 is divided by negative(-) 8 results negative(-) 3, which can be defined as +24/(-8) = -3
Question 5: Prove that [((-8) / (-4)] ≠ =-8 / [(-4) / (-2)]
Solution:
From the given question
[((-8)/(-4)]/(-2)] ≠ -8/[(-4)/(-2)]
First of all, we will consider the LHS part i.e., [((-8) / (-4)] / (-2)]
To solve the equation, first, we divide 8 by 4, we get the result as 2
As both numbers have a negative sign, it will be positive.
Then we divide the result (2) by -2, then the final result will be -1.
Therefore, the result of the LHS part is -1.
Now, we consider the RHS part i.e., -8 / [(-4) / (-2)]
First of all, we divide -4 by -2, the result will be 2.
As both the numbers have a negative sign, the result will be positive.
Now, divide -8 by the above result 2.
Hence, the result will be -4.
Therefore, the result of RHS is -4.
Hence, LHS ≠ RHS
The above given equation [((-8) / (-4)] / (-2)] ≠ -8 / [(-4) / (-2)] is thus satisfied.
Question 6: In a maths test containing 10 questions, 2 marks are given for every correct answer and (-1) marks are given for every wrong answer. Rohith attempts all the questions and 8 questions answers are correct. What is Rohith’s total score?
Solution:
From the given question,
The marks given for every correct answer = 2 marks
Marks given for 8 correct answers = 2 * 8= 16 marks
Marks given for 1 incorrect answer = -1 marks
Marks given for 2 incorrect answers = -1 * 2 = -2 marks
Rohit’s total score = 16-2 = 14 marks
Therefore, the answer is 14 marks.
Question 7: Priya sells 20 pens and some pencils losing 2 Rs in all. If Priya gains 2 Rs on each pen and loses 1 Rs on each pencil. How many pencils does Priya sell?
Solution:
Suppose that Priya sells x pencils.
Total gain on pens = 2*20 = 40 Rs
Total loss on pencils = 1x = x
Total loss on selling pens and pencils = (-2)
40-x = (-2)
40+2 = x
x = 42
Therefore, Priya sells 42 pencils.
Thus, the answer is 42 pencils.
Question 8: To make ice cream, the room temperature must be decreased from 45degree C at the rate of 5 degrees C per hour. What will be the room temperature 12 hours after the freezing point of the icecream?
Solution:
As given in the question,
Temperature after 12 hours = 12*5 = 60degree C
Room temperature = 45degree C
Hence, the room temperature after freezing process of 12 hours = (45-60)degree C
= -15degree C
Question 9:
A car runs at a rate of 50km/hr. If the car starts at 5 km above the starting point, how long will it take to reach 2505km?
Solution:
As per the question,
Total distance covered by car = (2505-5) km = 2500 km
Rate of car = 50km/hr
From the above values, Distance = 2500 km, speed = 50 km/hr
Therefore, the time required by the car = distance/speed
=2500/50 = 50 hours
Therefore, the car will take 50 hours to travel 2505 km.
Hence, The final solution is 50 hours.
Question 10: Jason borrowed $5 a day to buy launch. She now owes $65 dollars. How many days did Jane borrow $5?
Solution:
As per the question,
Jason borrowed a launch at = $5
Now she owes = $65
No of days = (-65) / (-5)
= 13 days
Therefore, Jane borrows $5 for 13 days.
Hence, The final solution is 13 days.

Question 11: Allen’s score in a video game was changed by -120 points because he missed some target points. He got -15 points for each of the missed targets. How many targets did he miss?
Solution:
As per the given question,
Allen scored points in a video game = -120
He got points for missed targets = -15
No of targets he missed = -120/-15 = 8 targets.
Therefore, he missed 8 targets.
Question 12: Karthik made five of his truck payments late and was fined five late fees. The total change in his savings of late fees was -$30. What integer represents the one late fee?
Solution:
As given in the question, Karthik has made five of his truck payments. Therefore, it is positive.
He was fined -$30 as the late fees.
To find one late fee, we have to divide the fine by no of payments he did.
Therefore, One Late fee = -$30/5
=-$6
Thus, He paid $6 for each payment as late fees.
Hence, the final answer is -$6.
